It features buried treasure, Volcanic eruptions, angry Mammy monsters, and suspicious locals who insist on speaking in this strange tongue they call Gaelic...

Gorgo opens with divers diving for treasure from a salvage vessel off the coast of Ireland. A vessel captained by a character called 'Joe Ryan' – played by the English actor Bill Travers, later famous as one of the leads in Born Free, and his first mate 'Sam' (American actor William Sylvester, probably best known for playing Dr. Heywood Floyd in 2001: A Space Odyssey).

They're diving near the fictional 'Nara' Island ('Nara' being Aran spelled backwards) when they witness these deep-sea, volcanic eruptions, which damage their vessel and forces them to dock on Nara Island (where they encounter suspicious, Irish-speaking, locals and an even more suspicious harbour master, called McCartin – who's afraid they might be after the viking ship full of loot he's discovered offshore).

So, that night, while a group of locals are out in currachs on a shark hunt, this Godzilla-like creature, Gorgo (brought to the surface from its deep-sea world by the volcanic eruptions) emerges from the waters and starts stomping off towards Nara island. Joe and Sam later manage to capture it and 2 palaeontologists arrive from Dublin and tell them to bring the creature back to Dublin for detailed study. But they ignore this order and set sail for London, where Gorgo is to go on public display in a circus in Battersea Park (with Joe and Sam handsomely rewarded for their troubles).

Evelyn O'Rourke is joined by Darryl Jones to chat about this week's Classic Movie 'The Long Good Friday'. It's a film about a ruthless East End gang lord called Harold Shand who is at a point in his life where he is trying to become a legitimate businessman.

Over a period of 20 years, the Film Noir era produced some darkly fatalistic and stylish work. Many of these films have become classics, whilst others have been lost to history. Detour, a 1945 low-budget film, has achieved cult status....and it is the Classic Movie choice of Stephen Boyd.

Our classic movie this week is a 1951 Ealing comedy with an extraordinary cast which includes Alec Guinness, Stanley Holloway and Audrey Hepburn. The Lavender Hill Mob, is the choice of guest Darryl Jones
